OIL-BURNER.

Specification of Letters Patent.

Patented July 1:3,1911.

Application filed November 2, 1909. Serial No. 525,881.

To all whom it may concern:

Be it known that I, MILTON A. FEsLER, a citizen of the Unitedffptates, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Oil- Burners, of which the following is a specification.

The present invention relates to improve ments in oil burners, the objectof the invention being to providea burner in which the supply of oil and steam passing through the nozzle may be regulated more-conveniently and effectively than heretofore, by which this supply will always escape at uniform pressure and also having convenient means for varying the size of the opening of the nozzle.

In the accompanying drawing, Figure 1 is a longitudinal section of the-burner, certain parts being -shown in side elevation; Fig. 2 is an end view thereof; Fig, 3 is an enlarged section on the line 3'3 of Fig. 1. Referring to .the drawing, 1 indicates a cross-shaped union, connected at opposite sides to the oil inlet pipe 2 and the steam inlet pipe 3. It-is also connected to the rear end of a steam conduit :4,- the'front end of which is screwed into the rear end of a nozzle 5, in which is pivoted, on atransverse pivot pin 6, a jaw '7 hav-ing'a' lip 8, forming, with a s tationa-ry lip9 upon the nozzle, a transverse slit through which the mixed steam and atomized oil can beejecteda Screwed in'an'openingin a partition 10 in said union is the inner end'of an oil conduit 11, which extends co-axially within the steam conduit, but terminates within said conduit to form a mixing chamber30. Said union is also formed, on the opposite side to that to Jwhichthe steam and oil conduits are connected, with a chamber 12, in

which can slide a ring 20, in which is screwed a valve tube 14, said tube sliding through. a. guideway formed in said cas ing" passing centrally within the oil conduit, and having screwed on its front end a conical valve 16. Said valve is adapted to seat itself against the front end of the steam conduit, and is pressed against said seat by a coiled spring 17 within the chamher 12, said spring being compressed be tween the guide 15 and said ring 20. lVithin said valve tube is contained a regulating rod or stem 19, the rear end of said rod passing centrally through a washer 13 anda stuiiing gland 21, and carrying on its rear end a crank handle '22. The front end of said rod is formed with an eccentric or U-crank 23, the front end of which is mounted 111 a bearing 24 formed upon the nozzle the eccentric portion thereofpa'ssing through a lug 25 depending from the jaw 7. Suitable packing 26 is behind the rounded rear end of said jaw 7.

)ne advantage of the above burner is its unlform action, due to the fact that the pressure-at which the mixture of steam and Oll escapes from the mixing chamber 30 into the atomizing chamber 31 is always uniform notwithstanding variations in the pressure ot'the steam or oil supplied. This escape by the pressure on 4 pressure is determined the coiled, spring, which I pressure the confined steam and 011 mustovercome in order to escape. A further advantage resides in the convenient construction for varying the width of the s lit through which the mix-' provided in a recess 27 ture of steam and atomized oil escapes from the nozzle, this being effected merely by turning the crank handle 22, the position of which crank shows, Width to which said slit I claim 1. In an oil burner, the combination of a steam conduit, an oil conduitv Within the steam :conduit, discharging into one end thereof, a valve tube within the oil conduit has been opened.

at a glance, the' and projecting beyond said oil conduit to i the end of the steam conduit, a valve on said tul e adapted to close the end of the steam,

conduit, :1. guide for said'tube, a coiled spring around saidv tube, and a device secured upon the end of said tube against which said coiled spring presses to close said-valve against the end of the steam conduit, substantially as described.

2. The combination of a cross shaped casing, having a partition, oil and steam pipes connected thereto on opposite sides of said partition, a steam tube connected to a third side, a-nozzle on the end of said tube, anoil tube within said steam tube and screwed into said partition, said oil tube terminating within the steam tube, a fourth side of the casing being arranged to form a guide and a chamber, a'valve tube guided in said guide and passing through said chamber and having a flange, a spring in said chamber between said guide and flange, and a "alve,'on

the o nher end of said valve tube, closing the end 015 said steam conduit, substantlally as to said nozzle, and a steni passing centrally through said tubes and connected eecentrb cally to said jaw, whereby the turning of said stem moves said jaw, substantially as described.

4. In an oil burner, the combination of co-axial steam and oil conduits, a nozzle secured thereto having a bearing, a jaw piv- 'eeaee through said tubes, the front end of said sltem being pivotally meunted in said hear:

ing, and said stem being eccentrically connected to said lug, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
